Nice job with the interior anti-aliasing of the hand. I would say to maybe cut out a color for the flames since it might be a tad unnecesary. That's me being a bit nitpicky though. The concept is really cool though.

You don't need a different colour for the nail! Use the shadow to pick it out, Luke!

thanks! its really, really late at night for me so i kind of rushed the flame, i should probably change that tomorrow, lol, i didnt add the nail because i didnt want to accidentally go over the color limit, but i have 3 colors to spare so i guess i can also do that when i revise the flame tomorrow

Sorry, but the solid flames makes it look like a one special toy for adults. You know. 

But I like the fist! It's very cool and menacing. Except for a thumb, which lacks the nail.
